Dwyer Instruments TSW-150 Temperature Switch
The Dwyer Instruments TSW-150 is a rugged Single Stage Weatherproof Digital Temperature Switch engineered for reliable performance in demanding environments like walk-in coolers, chillers, and wood boilers. This unit features a NEMA 4X (IP66) housing, making it ideal for outdoor or washdown-heavy technical applications. Operating with a 90 to 255 VAC power supply, it provides high-amperage switching via an SPDT relay rated for 20A at 240V and a 2HP motor load. The bright LED display indicates real-time process values and output status, while the internal hardware includes non-volatile memory to preserve configuration settings during power loss. Contractors can leverage the TS2-K configuration key for rapid setup of multiple units or use the front-facing keypad for field adjustments. For added security in public areas, the TSW-150 includes both a physical jumper lock and a software passcode to prevent unauthorized set-point tampering.
Key Benefits for HVACR Contractors:
- Universal Power Requirements: Operates efficiently across 90 to 255 VAC, reducing the need to stock multiple voltage-specific models.
- Enhanced Durability: The NEMA 4X enclosure ensures corrosion resistance and internal component protection in high-moisture settings.
- Heavy-Duty Switching: Features a high-capacity 20A SPDT relay, capable of handling 2HP compressors without an external contactor in many setups.
- Dual-Probe Compatibility: Field-selectable for both PTC and NTC thermistor inputs, allowing for flexible sensor integration.
- Tamper-Proof Design: Dual-layer protection via physical parameter locks and electronic passcodes ensures system stability.
Common Technical Questions:
What probe type is compatible with the TSW-150?
The unit is compatible with PTC (1000 Ω) and NTC (10 KΩ) thermistors. It typically comes with a standard TS-1 PTC probe unless otherwise specified.
How do I prevent "short cycling" on a refrigeration compressor?
You can program a minimum stop time and adjust the differential (hysteresis) settings through the internal parameter menu to protect the compressor from rapid cycling.
Can this unit be used for heating or cooling?
Yes, the TSW-150 features field-selectable heating/cooling control modes, making it adaptable for both brewing systems and refrigeration units.
